Silly schemes forgotten dreams of yesterday
amazing how they seem to pass us by
if everyone remembered all their yesterdays
tomorrow would be different this time
Spare a thought
and don't be caught by yesterdays
remember all your who, what, where and whys
learn by your mistakes and think of yesterday
and tomorrow will be different this time.
